ECC Group

Number of parity group where the LDEV belongs.

Output example: X-Y (decimals)

• If the number starts with “E” (for example, E1-1), the parity group contains external volumes (Hitachi Universal Volume Manager User Guide).

• If “LDEV Type” is Dynamic Provisioning or Thin Image, a hyphen (-) is output.
